My response is strictly from the perspective of my "Travelshooter" identity. 18 X 1.5 = 27 is not wide enough on a 18-55. Way too many times you can't zoom with your feet, so zooms are required for me on international tours. A great 10-24 would be wonderful and I will wait and see what the early adopters have to say. After that the choices are the Zeiss 12 and the Fuji 14.

As far as the 56 f1.2 ... I have a great 50mm f1.4 legacy Minolta (among a few others). With the 18-55, the 55-200, legacy 24 f2.8, 28 f2.0, 40 f2.0, 50 f1.4 , 80 f2.0 I think I have most needs except very wide angle covered although I would like the 35mm F1.4 and will probably add that lens too.

Probably get a XM-1 for the wifey so we will have plenty of good glass.
